UNITED STATES PATENT @FETCH WILLIAM H. LOVE, OF WASHINGTON, DISTnIcT OF COLOMBIA, ASSIGNOH OF ONEHALF HIS RIGHT To WILLIAM LEWIS HIPHINS, or SAME PLAGE.

Specification forming part of Letters Patent No. 209,696, dated November 5, 1878 5 I application filed September 28, 1878.

To all whom it may concern:

Beit known that I, WILLIAM H. LOVE, of Washington, in the county of Washington and District of Columbia, have invented a new and valuable Improvement in Fan-Motors; andl do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters v adapted for use in connection with an invalids bed or chair, or which may be applied to a stand carrying exposed food, the object in both cases being to drive away flies and create currents of cooling air.

The nature ,of the invention consists in combining with parallel fans having horizontal motion a fan having vertical vibration, the

said fans being all operated by a motor common to both, and each provided withfringes,where by a downward current of air is produced and a rustling motion of the fringes created, as will be hereinafter more fully Set forth and claimed.

In the annexed drawings, the letter A designates an upright frame, havin g an overhanging beam, B, andl erected on a oor or platform, B'. C2 represents a vertical-shaft, having its bearings in the 'beam B and platform B', and carrying on its upper end a masterwheel, C, and on its lower end a pinion, a, that engages the last wheel of a clock-train, D.

Eindicates an angular frame, rigidly secured to the extremity ofthe beam B, with its apex upward, and having journaled in its lower portion a rock-shaft, b, to which .one of the fanblades, e, is secured. The shaft b is provided,

with a rigid arm, b', that is connected flexibly t0 the lower end of a hanger, c, depending from a connecting-rod, O1, joined by a knee-connection c' to a pitman, D', attached, by means of a wrist-pin, d, to the master-wheel C.

The rod Cl is above the beam B, and reciprocates horizontally through the guides c', erected on the said beam, the function ofthe said guides being to direct the movements of the connecting-rod in right lines, and to cause the joint of the said rod and pitman to flex readily. At the free end of this rod, outside of the angular frame, is secured a transverse rod', El, of suitable rigidity, from' the ends of which depend the fringed fans G, and near the knee-joint c' is a second transverse rod, E2, having similar fans, Gr', depending one from each end.

The arm b' of shaft b is connected with a coiled sprin g, S, secured at the opposite end of the frameA by means of a rod, H, and ailexible cord, d', one end ofthe said cord being attached to the free extremity of spring S and the other to the end of rod H. The rod H is guided duringits movements by being carried through a staple, s, on the upright V, and its free end is supported by a vertically-vibrating hanger, 21 dependingfrombeamB. Atthepointwhererod H extends through the staple s it is bent in a flattened S-shaped form, theplane of the bend being horizontal, in order to produce a broad bearing on the guide s, by means of which thev said rod is prevented from speedily cutting through the said guide and wearin g the same away'.

When the clock-work is .wound up a horizontally-reciprocating motion is imparted to rod Ul, causing` the fans Gr G' on the rods E1 E2 to wave violently, their motion being horizontal. At the same time a vertically-vibratory motion is given to the fan e on the rockshaft b. This fan vibrates toward the fans G G', alternately causing a considerable currentof air, which suffices to cool the atmosphere.

At each forward movement of rod G1 the' spring S is coiled up, so that when the backward movement commences the said spring reacts, causing-the fans to be brought back with a jerk and the fringes thereon to rustle violently, thus effectually driving off iiies.

The fans may be used in connection with an invalids chair orbed, or to protect exposed food from ies. The speed of the fans is regulated, or they are stopped altogether, by means of a brake-lever, M, of angular form, the shorter arm of which extends beyond the shaft C2, and is shod with leather or other similar material. This lever is fulcrumed on the uprightV at y, and its leather-shod arm :r is forced int-o contact with theV said shaft Cz by depressing the power end thereof.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a iy-fan, the combination, with aframe, A, a vertical shaft, C2, master-wheel C, pinion a, and clock mechanism rotating said shaft, of the end frame E, carrying rock-shaft b, having a fan-blade, the connecting-rod Cl, having transverse rods E1 E2, carrying the fans Gr G', the hanger c, and arm b', connecting said rod Cl and rock-shaft b, as specified.

2. The combination, with a frame, A, a clocktrain, a vertical shaft rotated by said train and having a master-Wheel, G, on its end, an

angular end frame, E, its rock-shaft b, carrying a fan-blade, connecting-rod C1, the transverse rods El E2, having fans G G', the hanger c, and arm b', connecting said rod Cl and the rock-shaft b, of the coil-sprin g S, secured to thc frame, and a rod, H, connecting said spring and said arm b' of the rock-shaft b, substantially as speciiied.

3. The combination, with the frame A, having the end frame E, the rock-shaft b, carrying the ily-fan e, and a mechanism actuatingthe same, of the coil-spring S, secured at one end to the frame A, and connected at the other with said rock-shaft by the rod H and cord d', substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence ot' two witnesses.

WILLIAM H. LovE.
